Without delay… that’s how STS Line Maintenance services commercial and regional airlines operating out of U.S.-based major airports. We can do it, and do it efficiently, because our team has established a network of dependable line maintenance technicians who know your aircraft and understand the AOG cost of delayed response times.

At STS Line Maintenance, our main concern is, and always has been, the safety of your aircraft. We mandate compliance with all corporate, federal and local safety standards, and we make certain work is not just done but done properly.

A reputation for safety standards compliance, prompt service and highly skilled aircraft mechanics is precisely the reason why we’ve been the recipient of the FAA Diamond Award for aviation maintenance training!

Successful Partnerships

In January 2009, a major airline relying on STS to handle all of its Philadelphia line maintenance needs achieved a 100% on-time departure status with zero maintenance delays. Another airline enjoyed the three-month early completion of a major modification project performed on half of their fleet during overnight service checks thanks to the efficient teamwork of STS Line Maintenance, STS Component Solutions as well as the technicians working with STS AeroStaff Services. Impressive? Maybe… but these are only two of our countless success stories.
